Sluice Fixes:
1) Set soilType when throwing blocks on top
2) Bottom of sluice no longer eats blocks thrown on it
3) Fixed coreSampleStacks to contain one sample of each type of ore in range
4) Fixed exponential growth of output ore
5) Fixed addToInventory to check subtype so multiple types of ores and gems can be output
